Most of these supposedly true stories are made up by the UFO activists.

It has to be realised that there are many thousands of subversives, anarchists, 5th columnists, communists, call them what you will, out there whose avowed aim it to bring down elected governments and society as we know it. They in turn are bankrolled and funded by powerful shadowy figures who are plotting to take over when that happens. That is why they can produce quite expensive films and documentaries supporting their beliefs.

The UFO crowd are being "used" by these powerful people and they don't realise it, although the government does.

The finite speed of light means that we must always be out of date, no matter how hard we strive to keep up with the times. For distant galaxies, the light travel times are even longer, so our information about the galaxy NGC 6240, which is 400 million light years away, is 400 million years out of date! One consolation is that if astronomers on NGC 6240 are observing our Milky Way galaxy, they are likewise 400 million years behind the times - our times, that is.

Any distant galaxy observing our space activity in the 20C will do so millions of years in the future, A launch to investigate will take million of years to reach here. UFO's here and now - nah .......

I have discovered that lights at night can trick your brain into thinking you are seeing something you are not. Near my house is a TV/radio tower with four sets of lights as aids to aerial navigation. They are in a fixed position and blink at regular intervals. If I go outside and turn my head quickly in the tower's direction the lights appear to be moving for a few seconds. Of course I am not implying that the lights in Arizona may have been navigation beacons but it does show me that at night things are not always what they appear to be.Bob DeWoody

My motto: Never do today what you can put off until tomorrow as it may not be required. This no longer applies in light of current events.
